Well, December 2015 was when I announced here that I was going to rebuild what was basically a frame, fork, rear swing arm and shocks, and two fenders. Ha, only near 3 years later, I'm near done. Some used hubs and brake pedals restored. New electrical and ignition. Well pretty much everything was needed, and some stuff to restore. No need to list it all. I'm going for a resto-mod, but keep it stock like. My last purchase needed is a pirahna 140cc engine. I was able to find a performance muffler that's good to 180cc from CHP, but looks stock. The bike is coming along rather nicely so far. 20180915_170909 by 13andFreedom posted Sep 29, 2018 at 10:36 AM Question: can I use the stock throttle with a pirahna engine? Also, how important to upgrade from the 22m carb?
